and precautions before proceeding to operate the inverter.
Safety precautions are classified into the following two categories in this manual.
Failure to heed the information indicated by this symbol may lead to dangerous
conditions, possibly resulting in death or serious bodily injuries.
Failure to heed the information indicated by this symbol may lead to dangerous
conditions, possibly resulting in minor or light bodily injuries and/or substantial
property damage.
Failure to heed the information contained under the CAUTION title can also result in serious consequences. These
safety precautions are of utmost importance and must be observed at all times.
Application
• The FRENIC-Ace is designed to drive a three-phase induction motor. Do not use it for single-phase motors
or for other purposes.
Fire or an accident could occur.
• The FRENIC-Ace may not be used for a life-support system or other purposes directly related to the human
safety.
• Though the FRENIC-Ace is manufactured under strict quality control, install safety devices for applications
where serious accidents or property damages are foreseen in relation to the failure of it.
An accident could occur.
Installation
• Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
• Do not place flammable object nearby.
Doing so could cause fire.
• Inverters FRN0085E2S-4
or above, whose protective structure is IP00, involve a possibility that a human
body may touch the live conductors of the main circuit terminal block. Inverters to which an optional DC
reactor is connected also involve the same. Install such inverters in an inaccessible place.
Otherwise, electric shock or injuries could occur.
• Do not support the inverter by its front cover during transportation.
Doing so could cause a drop of the inverter and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter or from accumulating on the heat sink.
• When changing the positions of the top and bottom mounting bases, use only the specified screws.
Otherwise, a fire or an accident might result.
• Do not install or operate an inverter that is damaged or lacking parts.
• If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is installed in
the upstream power supply line in order to avoid the entire power supply system's shutdown undesirable to
factory operation, install a residual-current-operated protective device (RCD)/earth leakage circuit breaker
(ELCB) individually to inverters to break the individual inverter power supply lines only.
Otherwise, a fire could occur.
• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent
protection) in the path of each pair of power lines to inverters. Use the recommended devices within the
recommended current capacity.
• Use wires in the specified size.
• Tighten terminals with specified torque.
Otherwise, a fire could occur.
• When there is more than one combination of an inverter and motor, do not use a multicore cable for the
purpose of handling their wirings together.
• Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause a fire.
• Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds
500 kVA and is 10 times or more the inverter rated capacity.
Otherwise, a fire could occur.
• Ground the inverter in compliance with the national or local electric code.
• Be sure to ground the inverter's grounding terminals G.
Otherwise, an electric shock or a fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, an electric shock could occur.
• Be sure to perform wiring after installing the inverter unit.
Otherwise, an electric shock or injuries could occur.
• Ensure that the number of input phases and the rated voltage of the product match the number of phases and
the voltage of the AC power supply to which the product is to be connected.
Otherwise, a fire or an accident could occur.
• Do not connect the power supply wires to output terminals (U, V, and W).
• When connecting a DC braking resistor (DBR), never connect it to terminals other than terminals P(+) and
DB.
Doing so could cause fire or an accident.
• In general, sheaths of the control signal wires are not specifically designed to withstand a high voltage (i.e.,
reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live
conductor of the main circuit, the insulation of the sheath might break down, which would expose the signal
wire to a high voltage of the main circuit. Make sure that the control signal wires will not come into contact with
live conductors of the main circuit.
Doing so could cause an accident or an electric shock.
• Before changing the switches or touching the control circuit terminal symbol plate,
turn OFF the power and
wait at least five minutes for inverters FRN0072E2S-4
or below, or at least ten minutes for inverters
FRN0085E2S-4
or above
. Make sure that the LED monitor and charging lamp are turned OFF. Further,
make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+)
and N(-) has dropped to the safe level (+25 VDC or below).
• Be sure to mount the front cover before turning the power ON. Do not remove the cover when the inverter
power is ON.
Otherwise, an electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the auto-reset function has been selected, the inverter may automatically restart and drive the motor
depending on the cause of tripping. Design the machinery or equipment so that human safety is ensured at
the time of restarting.
Otherwise, an accident could occur.
• If the stall prevention function (current limiter), automatic deceleration (anti-regenerative control), or
overload prevention control has been selected, the inverter may operate with acceleration/deceleration or
frequency different from the commanded ones. Design the machine so that safety is ensured even in such
cases.
• The key on the keypad is effective only when the keypad operation is enabled with function code F02 (=
0, 2 or 3). When the keypad operation is disabled, prepare an emergency stop switch separately for safe
operations.
Switching the run command source from keypad (local) to external equipment (remote) by turning ON the
"Enable communications link" command
LE
disables the
key. To enable the
key for an emergency
stop, select the STOP key priority with function code H96 (= 1 or 3).
• If any of the protective functions have been activated, first remove the cause. Then, after checking that the
all run commands are set to OFF, release the alarm. If the alarm is released while any run commands are set
to ON, the inverter may supply the power to the motor, running the motor.
Otherwise, an accident could occur.
• If you enable the "Restart mode after momentary power failure" (Function code F14 = 3 to 5), then the
inverter automatically restarts running the motor when the power is recovered.
Design the machinery or equipment so that human safety is ensured after restarting.
• If the user configures the function codes wrongly without completely understanding this manual, the motor
may rotate with a torque or at a speed not permitted for the machine.
• Starting auto-tuning involves motor rotation. Sufficiently check that motor rotation brings no danger
beforehand.
An accident or injuries could occur.
• Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input
terminals L1/R, L2/S and L3/T, voltage may be output to inverter output terminals U, V, and W.
• Even if the motor is stopped due to DC braking or preliminary excitation, voltage is output to inverter output
terminals U, V, and W.
An electric shock may occur.
• The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the
specifications of motors or equipment beforehand.
Otherwise, injuries could occur.
• Do not touch the heat sink and braking resistor because they become very hot.
Doing so could cause burns.
• The DC brake function of the inverter does not provide any holding mechanism.
Injuries could occur.
• Ensure safety before modifying the function code settings.
Run commands (e.g., "Run forward"
FWD
), stop commands (e.g., "Coast to a stop"
BX
), and frequency
change commands can be assigned to digital input terminals. Depending upon the assignment states of
those terminals, modifying the function code setting may cause a sudden motor start or an abrupt change in
speed.
• Before proceeding to the maintenance/inspection jobs,
turn OFF the power and wait at least five minutes
for inverters FRN0072E2S-4
or below, or at least ten minutes for inverters FRN0085E2S-4
or
above
. Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure, using a
multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has
dropped to the safe level (+25 VDC or below).
Otherwise, an electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
Otherwise, an electric shock or injuries could occur.
• Never modify the inverter.
Doing so could cause an electric shock or injuries.
Disposal
• Treat the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.

*2 Even if the humidity is within the specified requirements, avoid such places where the inverter will be subjected to sudden
changes in temperature that will cause condensation or freezing.
Precautions for temporary storage
(1) Do not leave the inverter directly on the floor.
(2) If the environment does not satisfy the specified requirements listed in Table1.3-3 , wrap the inverter in an
airtight vinyl sheet or the like for storage.
(3) If the inverter is to be stored in a high-humidity environment, put a drying agent (such as silica gel) in the
airtight package described in (2) above.
[ 2 ] Long-term storage
The long-term storage method of the inverter varies largely according to the environment of the storage site.
General storage methods are described below.
(1) The storage site must satisfy the requirements specified for temporary storage.
However, for storage exceeding three months, the surrounding temperature range should be within the range
from -10 to +30°C (14 to 86°F). This is to prevent electrolytic capacitors in the inverter from deterioration.
(2) The package must be airtight to protect the inverter from moisture. Add a drying agent inside the package to
maintain the relative humidity inside the package within 70%.
(3) If the inverter has been installed to the equipment or panel at construction sites where it may be subjected to
humidity, dust or dirt, then temporarily remove the inverter and store it in the environment specified in Table
1.3-3.
Precautions for storage over 1 year
If the inverter has not been powered on for a long time, the property of the electrolytic capacitors may deteriorate.
Power the inverters on once a year and keep the inverters powering on for 30 to 60 minutes. Do not connect the
inverters to the load circuit (secondary side) or run the inverter.
Chapter 2 INSTALLATION AND WIRRING
2.1 Installation
(1) Installation Environment
Please install FRENIC-Ace
in locations which meet the conditions specified in “Chapter 1, 1.3.1 Usage
environment”.
(2) Installation Surface
Please install the inverter on non-combustible matter such as metals. Also, do not mount it upside down or
horizontally.
Install on non-combustible matter such as metals.
Risk of fire exists
(3) Surrounding Space
Secure the space shown in Figure 2.1-1 and Table 2.1-1. When
enclosing FRENIC-Ace
in cabinets, be sure to provide adequate board
ventilation, as the surrounding temperature may rise. Do not contain it
in small enclosures with low heat dissipation capacity.
Installation of Multiple Inverters
When installing 2 or more units in the same equipment or cabinet,
generally mount them in horizontally parallel position. When the
inverters are mounted vertically, attach partitioning boards to prevent
the heat dissipated from the lower inverter to affect the upper inverter.
For types smaller than FRN0072E2S-4
and for ambient temperature
below 40°C only, the units can be installed horizontally without any
spacing in between. (30°C or lower for HND and HHD)

(Note 1) Install recommended circuit breakers (MCCB) or residual-current-operated protective device (RCD)/
earth leakage breakers (ELCB) (with overcurrent protective function) on the inputs of each inverter
(primary side) for wiring protection. Do not use breakers which exceed the recommended rated current
.
(Note 2) Install recommended magnetic contactors (MC) as necessary on each inverter as these will be used to
disconnect the inverter from the power supply separately from the MCCB or RCD / the ELCB.
Additionally, when installing coils such as MC or solenoid close to the inverter, connect surge absorbers
in parallel.
(Note 3) When retaining the integrated alarm signal for the activation of the protective function at inverter main
power supply shut off is desired, or when continuous display of the keypad is desired, connect this
terminal to the power supply. The inverter can be operated without connecting power to this terminal.
(Note 4) The terminal does not need to be connected. Use this terminal when operating in combination with a
high power factor regenerative PWM converter (RHC series). (For types larger than FRN0203E2S-4
)
(Note 5) Remove the shorting bar between the inverter main circuit terminals P1-P(+) before connecting the
direct current reactor (DCR) (option).
ND mode: Types larger than FRN0139E2S-4
, HD/ HND mode: Types larger than FRN0168E2S-4
,
HHD mode: Always connect for FRN0203E2S-4
.
Use the direct current reactor (option) when the power supply transformer capacity is above 500 kVA
and the transformer capacity is over 10 times the rated capacity of the inverter, and when “thyristor
load exists” in the same power system.
(Note 6) Types smaller than FRN0072E2S-4
contain braking transistors, allowing direct connection of braking
resistors between P(+)-DB.
(Note 7) When connecting braking resistors to types larger than FRN0085E2S-4
, always add the braking unit
(option). Connect the braking unit (option) between P(+)-N(-). Auxiliary terminals [1] and [2] have
polarity. Please connect as shown in the diagram.
(Note 8) This terminal is used for grounding the motor. Grounding the motor using this terminal is recommended
in order to suppress inverter noise.
(Note 9) Use twisted lines or shielded lines for the control signal.
Generally, the shielded line requires grounding, but when the effect of externally induced noise is large,
connecting to [CM] may suppress the effect of noise. Separate the line from the main circuit wiring and
do not enclose in the same duct. (Separation distance of over 10 cm is recommended.) When crossing
the main circuit wiring, make the intersection perpendicular.
(Note 10) The various functions listed for terminals[X1] to [X5](digital input), terminals [Y1] to [Y2](transistor
output), and terminal [FM] (monitor output) show the functions assigned as factory default.
(Note 11) These are connectors for switching the main circuit. For details, refer to “2.2.7 Switching connector”.
(Note 12) The various switches on the control printed circuit board define the setting for the inverter operation.
For details, refer to “2.2.8 Operating various switches”.
(Note 13) Make the circuit breakers (MCCB) or the magnetic contactors (MC) trip by the thermal relay auxiliary
contacts (manual recovery).
(Note 14) Shorting bars are connected between the safety function terminals [EN1], [EN2], and [PLC] as factory
default. Remove the shorting bars when using this function.
Route the wiring following the steps below. (The inverter is already installed in the descriptions.)
2.2.2 Removal and attachment of the front cover and wiring guide

2.2.3 Precautions for wiring
Exercise caution for the following when wiring.
(1) Confirm that the supply voltage is within the input voltage range described on the rating plate.
(2) Always connect the power lines to the inverter main power input terminals L1/R, L2/S, L3/T (3 phase). (The
inverter will be damaged when power is applied while the power lines are connected to the wrong terminals.)
(3) Always route the ground line to prevent accidents such as electric shock and fire and to reduce noise.
(4) For the lines connecting to the main circuit terminals, use crimped terminals with insulating sleeves or use
crimped terminals in conjunction with insulating sleeves for high connection reliability.
(5) Separate the routing of the lines connected to the main circuit terminal input side (primary side) and the
output side (secondary side) and the lines connected to the control circuit terminals.
The control circuit terminal lines should be routed as far from the main circuit routing as possible. Malfunction
may occur due to noise.
(6) To prevent direct contact with the main circuit live sections (such as the main circuit terminal block), route the
control circuit wiring inside the inverter as bundles using cable ties.
(7) After removing the main circuit terminal screw, always restore the terminal screw in position and tighten even
if lines are not connected.
(8) The wiring guide is used to separately route the main circuit wiring and the control circuit wiring. In
FRN0072/0085E2S-4
, the main circuit wiring (lower level), the main circuit wiring (upper level) and the
control circuit wiring can be separated. Exercise caution for the order of wiring.
Case of FRN0072E2S-4
Handling the Wiring Guide
For inverter types smaller than FRN0072E2S-4
, the wiring space may become insufficient when routing the
main circuit wires, depending on the wire material used. In these cases, the relevant cut-off sections (see the
figure below) can be removed using a pair of nippers to secure routing space. Be warned that removing the wiring
guide to accommodate the enlarged main circuit wiring will result in non-conformance to IP20 standards.

(8) Depending on the inverter capacity, straight routing of the main circuit wires from the main circuit terminal
block may not be possible. In these cases, route the wires as shown in the figure below and securely attach
the front cover.
2.2.4 Precautions for long wiring (between inverter and motor)
(1) When multiple motors are connected to one inverter, the wiring length is the total of all wire lengths.
(2) Precautions for high frequency leak current
When the wiring length from the inverter to the motor is long, the high frequency current may flow through
the stray capacitance between the wires with various phases. The effect may cause the inverter to become
overheated, or trip due to overcurrent. Leak current may increase and the accuracy of the displayed current
may not be ensured. Depending on the conditions, excessive leak current may damage the inverter. When
directly connecting the inverter and motor, the wiring length should be kept to below 100 meters.
To operate in excess of the above mentioned wiring length, reduce the carrier frequency or use an output
circuit filter (OFL-
-
A).
When multiple motors are operated in parallel connection configuration (group operation), and especially
when shielded cables are used in the connections, the stray capacitance to ground is large. Reduce the
carrier frequency or use output circuit filters (OFL-
-
A).
Without output circuit filter
With output circuit filter
When the output circuit filter is attached, the total wiring length should be below 100 meters (below 400
meters under V/f control).
For motors with encoders, the wiring length between the inverter and motor should be below 100 m. The
restriction comes from the encoder specification. For distances beyond 100 m, insulation converters should
be used. Please contact Fuji Electric when operating with wiring lengths beyond the upper limit.
(3) Precautions on the surge voltage when driving the inverter (especially for 400 V series motor)
When motors are driven by inverters using the PWM method, the surge voltage generated by the switching
of the inverter elements is added to the output voltage and is applied onto the motor terminals. Especially
when the motor wiring length is long, the surge voltage can cause insulation degradation in the motor.
Please perform one of the countermeasures shown below.
Use motor with insulation enhancement (Fuji’s standard motors have insulation enhancements)
Connect a surge suppression unit on the motor side (SSU50/100TA-NS)
Connect an output circuit filter (OFL-
-
A) to the inverter output side (secondary side)
Reduce the wiring length from the inverter to the motor. (Less than 10 to 20 meters)
(4) When output circuit filters are attached to the inverter or when the wiring length is long, the voltage applied
to the motor will decrease due to the voltage drop caused by the filter or wiring. In these cases, current
oscillation and lack of torque may occur due to insufficient voltage.
